Indian Railways Schedule of Rates
About Indian Railways — IRUSSOR + Zonal SORs
Railway civil works — track formation, station buildings, foot-over-bridges, ROBs/RUBs, level crossings, platforms, electrical signalling structures — follow IRUSSOR for rate analysis. The apex IRUSSOR provides the methodology and item nomenclature; zonal USSORs (NR, WR, CR, ECR, ECoR, etc.) provide the actual rates for that zone. Engineers preparing tender BoQs reference both — apex for definitions, zonal for current rates.
Frequently Asked Questions
What is IRUSSOR?
Indian Railways Unified Standard Schedule of Rates — the apex rate document covering civil works (track, formation, bridges, station buildings, signalling structures). Issued every 4-5 years; 2021 is the current edition. Zonal USSORs derive from it with zone-specific input rates.
How are zonal USSORs different from IRUSSOR?
Item nomenclature, methodology and structure are identical. Input rates (labour, material, machinery hire) differ — zonal USSORs reflect that zone's market conditions. NR USSOR rates differ moderately from CR USSOR for the same item due to different input markets.
Which zones publish USSORs?
All 18 zones publish their own USSORs but discoverability varies. NR, WR, CR, ECR, ECoR, SECR, ER are well-indexed (linked here). NER, SCR, SR, NWR, NFR, NCR, KRCL USSORs exist but aren't always at canonical URLs.
Do metro rail projects use IRUSSOR?
Indian Railways-operated metros (Kolkata Metro Railway) use IRUSSOR. Standalone metro projects (DMRC, BMRCL, MMRC, CMRL, HMRL) use project-specific BoQs and don't publish unified SORs — each tender is self-contained.
Does DFCCIL use IRUSSOR?
DFCCIL (Dedicated Freight Corridor Corp) uses zonal USSORs for the corridors it intersects (WR for Western DFC, NR for Eastern DFC) plus its own Standard Schedule of Dimensions for civil engineering aspects.
